Abstract
L'invention entre dans le domaine des compresseurs. Compresseur rotatif vertical étanche à vis supprimant la nécessité de l'utilisation de pistons de compensation de poussée et de pompe à huile par un arrangement spécial de paliers étanches à rouleaux coniques, la pression de refoulement du compresseur faisant migrer l'huile transportée par le fluide de travail à travers les paliers vers le côté admission basse pression du compresseur. L'invention s'applique aux compresseurs verticaux à rotors à vis s'engrenant l'un dans l'autre.
